Zhongxian used to belong to Wanzhou.

Now, except Liangping and Chengkou, which are directly under the jurisdiction of Chongqing (one is relatively rich and the other is extremely poor), other districts and counties are managed by Wanzhou immigrant area. I have forgotten the exact source of the news, but it is true. It just seems that there is no need to pay taxes to Wanzhou now.
